Unreferenced field in simple day view with no sidebar

Hi again
I can probably unpick this and figure - but I know tweaking about in the tabs and various layers of fields can be tricky - I've read (most) of your very good documentation. So any help in identifying which field/ layer this unreferenced field is lurking would be gratefully received. Looks like where the event status should be? Only a problem when sidebar is collapsed. Promise I haven't done mod to this layout - it was like this.
